Be 1t known that I, lVAL-LACE Vinson, a

citizen ofthe United States, and a resident of the city and county of Denver, in. the

State of Colorado have invented certain new and useful Improvements n \Vater- Heaters, of whlch the following 1s a full,

clear, and exact description, such as will enableothers skilled in the art to which the invention appertains to make and use the same.

MyQinvention relates to improvements in water heaters, and the inventionhas for-its object the provision of a 'water circulating medium which may be applied to a cook ing stove, or other heating .unit for the utilization of the heat eminating from the stove, or other heating unit for the purpose of heating Water.

Another; objectzof the. invention is to provide means forutilizing the same heat 7 used for cooking, or other purposes for heating water, thereby obviating the necessity of employing an independent heating source for thewater. v

Another objectof the invention is to provide means for. application to a stove, Without altering the construction of the stove, for utilizing the sameheat units to heat water, and wliicliineans will not interfere with the primary use of the stove or in anymanner detract. from the efliciency of the stove in its primary use. With these and other objects in view, the invention will be described with reference to the accompanying drawing, which forms a part hereof. v

In this drawing Figure 1 is a. plan view of a cook stove, showing the water heating attachment applied thereto; Fig. 2 is an elevational view of the storagetank used in connection with the invention; Fig. 3 is an enlarged plan view of one of the circulating units; and Fig. 4 is a cross sectional View of the circulating unit, taken on the line 4%, Fig. 1.

Corresponding and like parts are referred to in the following description and indi cated in all the views of the accompanying drawing by the same reference characters. Let the numeral 5 represent a cook stove which employs gas as the fuel, the same being provided with the usual burners 6, above which a grating 7 is disposed. This grating 7 is usually removable with convenience. The numeral 8 designates the water circulating unit in its entirety. One of these units is positioned aboveeaeh burner 6 below the grating 71, and the circulating units arefl all connected in communication with "each other by means of the connecting pipes 9, l0 and 12. A supply pipe 13, leading from the bottom or the storage tank 14, communicates with the first circulating unit 8 of the series, while an eduction pipe 15 leads from the last heating unit 8 into communication with the upper extremity of the storage tank 1 1'. A feed pipe 16 supplies the storage tank 14:, the same entering the top of said tank and having its discharge extremity extended close to the bottom of said tank, whereby the water is discharged from the feed pipe 16 in the bottom of the tank. Thus, in operation, the water passes from the bottom of the storage tank 1 1 through the supply 13, circulating through he circulating units 8 in succession and flowing back lnto the top of the storage ftankl through the eduction pipe 15. The .water is heated by the influence of the understood that they may be made of any suitable shape and form, so long as the principles of the invention are conserved in the construction of the same. There are, however certam elementary features of construction. upon which the efficiency and best results from the invention depend, and to which, much importance is attributed. These features will become apparent in the following detail description of the construction and form of the said circulating units. An outer pipe 18 of triangular shape in cross section isincommunication with nipples 19 and 20, which nipples are diametrically arranged and receive the connecting pipes heretofore described, the said nipples being interiorly threaded to cooperate with threads on the extremities of the said connecting pipes. Transverse parallel arranged pipes 21 and 22, also of triangular shape in cross section, communicate at their extremities with the outer pipe 18, their communicating points being adjacent the nipples 19 and 20, whereby the water, immediately upon entering the heating unit 8, is distributed through the pipes 18, 21 and 22 and again comes together at the eduction nipple and is discharged Patented Dec. 4t, 1917..

through the communicating pipe into the succeeding heating unit, wherein it is again distributed through the various pipes thereof. The pipes 18, 21 and 22 are spaced apart to form relatively narrow openings through ,7

said pipes. The triangu'lar shape of the pipes 18, 21 and 22, which are positioned on the heating unit so that two sides of each of the "pipes converge inwardly toward the burner, cause these spaces to widen out to ward the lower side of the heating unit and at the same time to expose a maximum area of said pipes to the influence of the heat.

For convenience and .for the sake of a more definite description, these relatively narrow openings will be designated 28,- 24 and 25.

' natural result when auxiliary appliances "are used, the construction of this circulating unit increases'th'e etficiency as well as to minimize tlieconsumption of gas by the thorough mixture of air therewith. The

heating unit is of sufiicient area to entirely cover the burner, thereby forming a housing 'through which a draft is created in substan- 'tially the same manner as through the ordinary fire box, the circulating unit entirely confining the flames below the same in the space between'the latter and the burner.

By the use of myinvention, the same heat employed for cooking is used to heat water, and the employment of auxiliary, or independent water heating means is obviated, re-

. sulting'in a great savingof fuel.

' further. advantage of the invention resides in the prolonged retention of heat on the cooking stove, whereby foods may be left on the stove and kept warm by the hot water in the circulating units for a considerable length of time.

While I have described and illustrated a specific form of the invention, it is understood that the same may be modified and varied without'departing from the spirit of the invention or the scope of the appended claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. The combination with the burner of a cook stove, of a fluid circulating unit disposed above said burner and occupying an area equal to the area occupied by said burner, said circulating unit comprising an outer pipe forming a continuous elliptical passage, nipples mounted on said outer pipe and with which the latter is in communication, said nipples being disposed opposite each other, and parallel connecting pipes communicating at their extremities with said nipples and disposed in substantial alincment with said nipples.

2. The combination with two burners of a cook stove, of a fluid circulating unit disposed above each of said burners, said circulating units each comprising an outer elliptical shaped pipe forming a continuous passage, an induction and eduction nipple connected with each of said elliptical shaped pipes of said circulating units a pipe conin the presence of two witnesses.
